So, I was trying to repair some cosmetics from a stupid drop I had last season (the cantilevered bit which holds the pillion peg broke off at the pillion area) but I ended up not being able to crack one of the allen bolts after hurting my hands.

Anyway, in trying to take this off, I undid the brake mechanism. I was careful (or thought I was) putting it back on; and the rear brake activates satisfactorily, but when I depress the rear brake lever the light does not come on. The front brake lever does trigger the brake light.

Any thoughts or suggestions?

Not familiar with this model. Some have a weird linked brake setup. I assume not and hydraulic! So probably pulled the plug off the pressure switch or damaged a wire.

I think it's called the BN300 elsewhere? And I think related to the 250 or something that exists in a few other countries.

I'm unfortunately relatively new to riding. The brakes are definitely hydraulic but there's like a pin that presses into a housing to activate them off the lever. I'm getting brake application.
Worst comes to worst, I'll just take it to a shop to figure it out. Definitely want to stay safe.

On hydraulic systems there is usually what looks like a large bolt screwed into the end of the hose with 2 wires attached this is a pressure switch. Maybe looks like this

Yea, I guess I'll have to get out a multimeter and check out the switch. Visual inspection seemed okay yesterday.


I appreciate it. Is there anyway I can try to manually activate the switch?

EDIT:

Yea,here's what the switch looks like. So you're spot on.

No if your brake is working ok then pressure is being created and it should work. If it has been disturbed then I would suspect wiring problems

Yea.Doesn't seem like there's air in the system. So I'll have to try a jumper or multimeter and go from there. Thanks for your help.

EDIT: Jumper still engages the brakelight, which is what I expected. So something's up with the switch. I'll have to try to determine what. Hopefully when it's less wet.

Alright, so, in trying to mess around with it I accidentally bumped one of the brake lines loose. Put them back on, but now even with a vacuum tool I can't get them to build pressure. Guess I'm taking it to a shop, heh.
